'2 Claims.

HOurinvention relates to surface condensers,

more particularly of the marine type, and it has for an object toprovide a condenser with beam members connected thereto andwhichfunction, not only to support the condenser, but to cooperate with thelatter to provide a supporting or bed construction for turbines and thelike.

A further object of our invention is to provide a condenser having itsshell welded to end plates .constituting webs of supporting beam memberswhose outer ends are carried by supports, the

beam members'belng attached to the supports at one side of the condenserso as to resist movement of the beam members bodily in .the direcfree tomove horizontally with respect to the supports at the other side of thecondenser to accommodate expansion and contraction thereof as well as of.the condenser. I

These and other objects are effected by our invention as will beapparent from the following description and claims taken in eonnectionwith the accompanying drawings forming a part of this application, inwhich:

Fig. 1 is a top plan view of a power plant incorporat-ing the improvedcondenser arrangement; Fig. 2 is a side elevation of the apparatus shownin Fig. l with a portion of the casing structure broken away to show thegearing and the cou- Dling;

ratus shown in Fig. 1;

modified arrangement;

Figs. 5, 6, and 7 are detail sectional views taken Fig. 2; and,

lines VI1'IV1II and IX-IX of Fig. 4.

Referring to the drawingsmore in detail, there is shown a condenserhaving a shell III enclosing a nest of tubes ll connected to tube platesl2. The shell I is welded to end plates 13 to which the tube plates I 2are connected by stud bolts M, the latter also preferably holdin'gthewater boxes IS in place with respect thereto. The 'end plates l3constitute widened intermediate portions [6 of the webs l-l of the beamsor girders, at 18, the beams or girders being constituted by the websand by suitable strengthening and stiffening flanges l9.

As shown, the beams or girders l8 have their supports 20 formed on thecasing 2| of the reduction gearing, at 22. The ends of the beams carriedby supports 23 formed by any suitable tions of their length and the beammembers being Figj3 is an end elevational view of the appa- Fig. 4 is aview similar to Fig. 2 but showing a alongthe lines V-V, VI'-VI andVII-VII of Figs. 8 and 9 are detail views taken along the coplanar withor parallel to the webs ll.

other ends of the beams it! in Fig, 4 may be slidends, at one sideof thecondenser, carried by or girders, at theother side of the condenser arevenient means for supporting apparatus, for ex-v example, thehigh-pressure turbine-25 andthe low-pressure .turbine 26.. Preferably, across beam 21 is arranged between the beams l8 and connected thereto.The condenser shell l0 car-v ries a supporting structure 28 spacedfrom'and arranged substantially parallel to the cross beam 21.

. The high-pressure turbine is supported at the end adjacent to'the'gearing by means of a pedestal}! carried by the cross beam 21 and at-theother end by means of aflexible I-beam section 30 mounted on thestructure 28, the I-beam section having-its web arranged transversely ofthe turbine and being, therefore, capable of flexing -to accommodate-foraxial expansion and contrac- .tion of the high-pressure turbine.

turbine and flexing to provide for expansion and contraction, theexhaust end of the low-pressure being free to slide endwise andlaterally on the I supports 23. 'In this embodiment, therefore, t hebeams l8 are capable of expanding and contracting lengthwise withrespect to the supports 20 and they have sufllcient inherent flexibilityaxially of the condenser to accommodate for expansion and contraction ofthe condenser shell.

In the second form of our invention, the neces-' sity for the smallamount of flexing onthe part of the beams I8 to accommodate expansionand contraction of the condenser is avoided or very largely reduced bymeans of the I-beam sections 36 fastened to the supports 20 and havingadjacent ends of the beams l8 secured thereto, the

I-beam sections 36 having their webs arranged The hold the turbines inpredetermined relation with.

Accordingly, in the embodiment shown in respect to the reductiongearing, other provisions shouldexist torestrict the condenser and beamaggregate from shifting laterally at the end remote from the reductiongearing and disturbing the relation of the turbines and the gearing aswell as the relation of the condenser to its auxiliaries. Accordingly,we provide plates 40 attached at one end to the ship's structure at 4].

'ed by couplings capable of accommodating misalinement. 'For example, inFig. 2, we show the spindles 32 and 33 having their adjacent endsvprovided with peripheral teeth 42 and 43 encompassed by a muff member 44having internal teeth meshing with the teeth 42 and 43, the muifmemberbeing of adequate length-to take care of any misalinement.

While we have shown our invention in several forms, it will be obviousto those skilled in the art that it is not so limited, but issusceptible of various changes and modifications without departing fromthe spirit thereof, and we desire, thereiore, that only such limitationsshall be placed thereupon as are imposed by the prior art or as arespecifically set forth in the appended claims.

What we claim is:

1. In a power plant condenser arrangement,

. supports arranged to provide a space therebetween; a pair of spacedbeam members providing a supporting bed construction, spanning saidspace, and having their outer ends carried by said supports; and acondenser including a shell located in said space and end plates for theshell formed by webs of the beam members.

2. In a power plant condenser arrangement, supports arranged to providea space therebetween; a pair of spaced beam members providing asupporting bed construction, spanning said space, and having their outerends carried by members, a nest of tubes within the shell. tube platesfor the tubes, water boxes, means for securingthe tube plates andthewater boxes to the end plates formed by the beam member webs,

means for; supporting the outer ends of the beam members at one side ofthe condenser so as to re- 1 sist bodily movement thereof lengthwise,and means for supporting theouter ends of the beam members at theother'side of the condenser so as to provide for movement thereofhorizontally in any direction.

4. The combination with a power plant condenser, of means for supportingthe condenser including a pair of. beam members, said beam membershaving intermediate and depending widened portions joined to the ends ofthe condenser, means for supporting the outer ends of the beam membersat one side of the condenser so as to resist movement thereof bodily inthe direction of theirlength, and means for supporting the outer ends ofthe beam members at the other side of the condenser so as to provideformovement thereof to accommodate for expansion and contraction of thecondenserand for contraction and expansion of the beam members in thedirection of their length.

5. The combination with a power plant condenser, of meansior supportingthe condenser including a pair ofbeam members having intermediate anddepending widened portions joined to the ends of the condenser, firstsupports for the ends of the beam members at one side of the condenser,second supports for the ends of the beam members at the other side ofthe condenser, and means for attaching the first supports to thecorresponding ends of the beam members to resist movements thereofbodily in the direction of their length, said second supports and thecorresponding ends of the beam members being constructed and arranged toprovide for movement of the beam members so as to accommodate expansionand contraction of the condenser and of the beam members in thedirection of their length.
